The transfer conduit T includes the trough member 20- which is provided with a saddle member 23 intermediate its ends. The saddle member 5 term is installed on the locomotive and its tender 23 is rigidlyseoured to the trough member and to permit of movement'between the rearward or 'hasa flat plate-like-portion Z'depending there- I transfer conduit section and the tender, while, from which rests'upon a bracket 25 rigidly se at the same time, providing for all other movecured to the tender frame 16.

In its more specific aspect the object of this. invention contemplates the provision, in a stoker having a novel transfer conduit disposed on the tender as described, a novel relation of the, fuel conveying conduits which consists in joining one end of the stoker intermediate to the riser con duit of the locomotive, while the other end of the intermediate conduit is jointed'to the fuel transfer conduit so as to swing upon a transversely extending axis.

These and further objects which reside in the permit the saddle member 23' and the trough member 20 to pivot about the shaft 27 andmove longitudinally with respect to the tender and bracket 25 and'at the same time, prevent any vertical movement ofthe trough with respect to the tender frame 16. The trough member 20 may be further supported by pedestals such as 30 which 7 may be secured either to the bracket 25 as shown 7 or to the tender frame 16, the trough member:20

thereby forming a ball and socket connection at this point. The riser conduit inclines forwardly and upwardly from this connection and delivers fuel through the firing opening 13 of the backhead 12 to which the riser conduit is rigidly secured as by means of the support bracket 47. The upper end of the riser conduit forward wall 48'extends into the firing opening and supports a pressure fluid head 49 which serves to distribute fuel over the firebed from the distributing conduit of the conveying system S.

Suitable means for advancing fuel through the conduits are provided and include a screw c onveyor such as 51 which is revolvably mounted in the trough members 20 and universally connected as at 52 to a screw conveyor 53 of the intermediate conduit 22, the screws beinguniL In the modified form shown in Figure 3, a screw.

conveyor 54 is mounted withinthe riser conduit 21. Thisscrew is universally connected to the screw 53 of the intermediate conduit 22 as at 55, preferably at the'joint between these conduits. A bearing 56 may be provided for the upper terminus of the screw 54.

It will be apparent that a fuel conveying system of novel form has beenprovided which has ample meansfor providing for the necessary vertical and horizontal movement between the locomotive and tender units of the stoker when the locomotive and tenderv are negotiating curves, cross-overs or turntables. This is accomplished by mounting the trough member 20 to swing about a vertical axis or shaft 27 and move longitudinally of the tender by means of the slot 26 in the bracket 25 to providefor any horizontal movelhe vertical movement betweenthe riser conduit 21 and'the trough member20 isprovided by universally connecting the forward end of the intermediate conduit 22 to the rearward portion of the riser conduit21 and mounting the rearward portion of the intermediate conduit to swing upon a horizontal transversely extending shaft 39 passing through the novel connecting member 32 of the trough 20.

The function of the modified form of the invention is the same as that of the preferred form, the modified form illustrating but one of the advantages of this novel 'arrangementiof the conduit system. By the use of this modified form of the invention, it is possible to support the'upper terminus of the screw. 54 of the riser conduit 21 by a bearing56 without the-use of any telescoping sections in the screw conveyors. vThis is accomplished by permitting the trough members to move longitudinally with respect to-the tender 15, thereby maintaining a constant length of the fuel conveying system S from the riser conduit 21 rearwardly.
